To all whom; it may concern A Be itknown that I, JOHN J.-'G1Li.nsrm, a,

ton, in the county of Suffolk and ommonw'ealth of Massachusetts,have 'invented cer tain Improvements inl Coating-:'Machines, ofwhich the following description, in connec#V tion with the accompanying drawings, is a specification, like. reference,- characters Aon the drawingsindicatin'g like parts in the several figures. y

This invention. relates to y,machines for coatingmaterial and particularly for coating parts of shoes such as linings for Vamps with cement. By the term cement is meant any material o 'a cementitiousnature such as ordinary cemi'ent, paste or other adhesive Y substance.

In vhe manufactureof shoes itis vfound desirable to stick together certain parts such as Vamps 'and vamp-'linings .inorder that \thes"e parts may be kept in accurate position relatively to each other during the assem lbling andrstitchin'g operations. lt: is c ustomary'to ,coat lining's'such as vamp-linings' withgcem'ent on onejside vand then place the lining-in the "proper position'A upon the vamp or other part with-the coated 'side in contact therewith. Difficulty is sometimes experienced in getting the proper amountof 'ce ment upon the lining` and also in applying it in a uniform manner. If too much cement isv applied, the lining is apt to pucker unless great care is takenA to smooth it down upon the part to whichv it is cemented.

, Furthermore, when too much cement is ap-,

plied, it will get on the fingers ofthe operator'and will smea'r portionsof the shoe which itis particlarly desirable to eep clean. On'the other hand if an insufficient quantity ofv cement is'applied the .parts will not adhere to each other.' If the cement is not applied uniformly the lining is apt to Specication of Letters latent.

AnobJect of this f invention is to provide 'I a machine which will apply cement to one '1 Side 0f the material which itisdesired .t0-

.coat without liability of thematerial clingingv to the applying means.

Another obJect'offthe invention is to pro'- vide amachine in'which a sufficient quantity l of cement will be applied to the material without liability-of applying a'n excessive amount.- A 1;; f

A further object of the invention is so to construct the machine thatsmearing of the material with cementupon'- the portion which it is desiredito leave uncoated is pre-7 One ofithese objects is accomplished Y constructing 'a machine Lwhichhas a- -recep'v tacle for 'cement-divided, into compartments bygone or more partitions," and which has applying'means associated .with one 'of the" ,compartments` vTheapplying-5: means may lconsist conveniently -o aA rollerrotatably mounted in one compartment. This compartment is connected withthe other compartments in which the cement is p lacedby ad`l justable passageways. vBy adjusting the passageways the flow'of cement tothe applying means may be so controlled that said'means will take up approximatelyv Vthe proper amount of cementto give the desired coating. It is preferable, however, so to adjust theV passageways that the applyingroller will takeup slightlyumore cement than is desired and then to remove this slight eX- cess by means of a' scraper or doctor before the saidv roller comes into contact withthe materiali to be coated'. Means consistingpreferably of a pressure-roller'may be pro-lV i vided to press the material into contact with the applying means and thereby assist in l obtaining a uniform coating on the mate-A rial. Means tp prevent the materialfrom being smeared on the side which it is de- Vsired to leave uncoated is preferably associated with the pressingmeans.

A convenient construction for this purpose consists of a trough having `a scraping edge in contact with lthe pressure-roller. Means for guiding the material to the applying means may be provided. The said guiding means is preferably so arranged as to 'extend in substantially the s ame planeas the means for preventing the material from clinging to the applying means- A, f The means for preventing 4the material from clinging to the applying-roller consists preferably of a frame having4 relatively small wires stretched acioss it at intervals from side to side. This frame is securedto the machine in such lmanner that the wires `extend between the pressure-roller and the applying-roller with the wires in contact with and practically embedded in the feltwith which-the applying-roller may be covered. Since thev material when it passes through the machine has the ressure-roller on one 4side andthe applying-roller and wires on the-other side it will be seen that not only will Athe material be prevented from clinging to the applying-roller but that the wires will not interfere with coating the material o n substantially the 'whole surface which is adjacent to the' applying-roller. In order that the material may be fed expeditiously a table is preferably supported atthe front of the machine abutting against the frame for the wires and extending in the same plane therewith.

vReferring to' th -drawings, Figure 1 is a sectional view of the machineon the line :z2-w, Fig. 3'; Fig.l 2 is a view inperspeetive of the upperportion of the machine Fig. 3 is a top plan View; and Fig. 4 is a view in elevation of the right-hand en d ofthe ma-- chine. i

A base plate 2- carries standards 44,*4.

Upon the base plate and between 'said-standards is a receptacle o rtaiik 6. applyingroller 8 which istprefeiablyf covered with felt is mounted in bearings on the standards. This roller is'mounted to rotate within said receptacle with its lower portiona slight dis- Y tance above the bottom of thel receptacle.

Y cally slidablc.

Above the applying-roller is apres'sure-roller l0.V These two rollers are so mounted as to be relativelyadjustable. As shown in the drawings .the shaft `of the pressure-roller is mounted in bearings 12 which-- are sosupported on the standards '4, 4 as -to be verti- The-amount of separation between the two rollers -is regulated by the thumb nuts 14 which screw upon the upper ends of boltslG which are secured at -their lower ends to the said bearings The receptacle is divided into compartments, there being three as shown. compartments are formed by partitions 18 hingedat their upper ends to the receptacle. Rods 20 are secured to the 'lower ends of the partitions by means of joints 21. The upper ends of these rods are screw-threaded, and thumb-nuts 22 which engage the screw threads are rotatably secured to sleeves 24 pivoted to brackets 26 secured to the receptacle. The nuts are -prevented from longitudinal movement by the said sleeves and hence by turning the nuts the Vrods may be Thev raised or lowered as desired and the partiltions opened to any desired extent or entirely closed.

The shafts of the applying-roller and the pressure-roller have intermeshing gears 28 and 30 while the shaftof the applyingroller also-has adriving-pulley 32. 'lhis pulley loose on the shaft and 'may be connected thereto when desired by afclutch 34.4 The teeth of the intermeshing gears are made sufliciently long to be. kept in mesh when the sition desired.

The standards 4, -l have'bracketsSG which.

carry a scraper or doctor 38 to remove surplus cement from the applying-roller. Se cured to the Istandards above said'bi'ackets are rabbeted supports 40. To' these supportsis secured a rectangular frame 42 having wires 44 stretched acrossit at intervals between the two rollers. A board or table 46 rests upon the supports 40, the rear edge of said table abutting -against 'the front edge of the rectangular frame 42. The upper sur- .face of said table liesv in the same plane as pressureroller is adjusted to the highest pothe hangers. The vtrough has afscraping edge 54 and the bottom" offthe trough is Apreferably inclined downwardly from-,the center toward each end, and securedto each end is conduit 56 which leads to the receptacle 6.

The table 46 .and the doctor 38 are provided with aperturesfor the conduits which-.preferably terminate on about the level ofthe doctor. l

The machine may be Ataken apart readily for cleaning or other vpurposessince the parts are removably secured. The trough with attached conduits is removablyv supported in thehangers 48 while theJ frame for the wire is removably supported upon the rabbeted support 40 as 'is also the table.

'The standards are bolted to the base and by loosening them, 'the applying-roller and the pressure-roller may be removed. y

The operation'of the machine is as follows: The operator places cement `in either or both f tthe outside compartments of the receptacle and 'adjustsl thev partitions 18 to permit a slow `flow-of cement into the middle compartment which contains the applying-roller. The flow is preferably so regulated that the lower portion of said roller extends for but a slight distance into the cement. The roller therefore. does not'carry up a large excess of cement and the amount carried Yupvwill always be the same ,for la particular quantity of cement regardless of ments. It is intended that the applyingroller shall take up slightl more cement than is needed and this slig t excess is removed by the doctor 38. The pressure-roller 10 is preferably adjusted by turning the thumb-nuts 14 if this has not already been done. This roller is preferably of brass or similar composition,and is made very smooth. It is therefore possible to adjust it so as to bring it very close to the applying-roller without bringing it into actual contact therewith. Cement is not liable therefore to get on the pressure-roller, but if it does it is quickly removed by the scraping edge 54 from which it iows mto the trough and then back to the receptacle throu h the conduits. Smearing of the materia upon the upper surface 1s thus prevented since if any cement gets upon the roller 10 it is removed before the roller comes into contact with the material. When the operator is ready to commence coating the material, he throws in the clutch and presents the pieces to be coated, one at a time, so that the edge comes between the pressure and applyingrollers which rotate in the direction indicated by the arrows in Fig. 1 and act as feedrollers to cause the materlal to ass between them. As the material which 1s designated by the character a in Fig.r2 passes between:

the rollers in the direction indicated by the arrow in said figure, it is coated uniformly,

upon the lower side by 'contact with the applying-roller and is prevented from clinging to the same by the wire which 1s stretched across the frame 42. The pieces to be coated may be piled within easy reach of the o rator when standing in frontof the machine. He picks them u one at a time and places them upon the ta le upon which they are guided to the rollers. The individual members of the wire are suiciently small to be practically embedded in the felt of the applying-rollerY and hence no portion of the lower surface of the material ,is left uncoated.

As has been stated above, the position of the pressure roller 10 may be varied by turning the nuts 14. In the use of the machine these nuts are turned until the effective ortion of the pressure roll is at a distance rom the plane of the wires equal approximately to the thickness of the vamp which is to be cemented, so that the vamp lies flat during its assage through the machine.

aving described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A machine of the class described having in combination a cement applying roll, means for supplying cement thereto, a pressure roll, a presenting table having its upper surface in a plane extending between the surfaces of said rolls, a frame comprising a plurality of wires` located in sald plane, and a guideway in which said table and frame are slidable.

2. In a machine of the class described, the combination with a receptacle for cement, of a partition hinged at its upper end to the walls of said receptacle and dividing said rece tacle into two compartments, a rod pivotedp to the lower end of saidpartition and means for adjusting said rod.

In testimony whereof I have signed my `name to this-specification in the presence of two subscribing witnesses. A JOHN J. GILLESPIE. Witnesses:
